Anything that says "ENO*" might be interesting.

Use your intuition!  Since I removed all the memory (un)mapping and brk-ing,
you should be familiar with a lot of what's going on.

That's normal.  sb.o depends on sound.o, but sound.o does not depend on
sb.o.
 
Wild stab in the dark -- do "depmod -a".

The sb module is certainly not behaving.  Do the strace and look at it.
You'll know if something is wrong.  I'm wondering if it's a kernel
dependency bug?
